[phenixbb] helical structure - Real space refinement

[Pavel Afonine]

Hi Dmitry,


if your model is composed of chains related by some rotation/translation 
(does not matter what symmetry), you can ask Phenix real-space 
refinement to identify and use that symmetry as "NCS" constraints (yes, 
NCS is a legacy term from Xtallography!). Aprart from this there isn't 
anything particular.. Alternatively, you can manually specify the master 
and symmetry related chains when setting up refinement job.
